I am not angry, I just think you are stupid. Why do you care about where the data center is for access via REST API and a brokerage that sells your order flow? As many long-term and successful traders on this site already pointed out a brokerage that charges a fixed amount for equity executions such as Tradier has no other way to make money than selling your order flow. For that purpose it really could not matter less where the firm's data center is located at. Thats why I pointed out it was a very stupid question to ask.
Ha, dude I love how angry you are 100% of the time. For some reason it makes me happy. Thanks.
